After some time of watching videos on YT via Firefox, doing something else in other program and returning to FF, the sound level gets very nasty, past the clipping-level. It's very loud and noisy. It's impossible to recover from that - the only solution is to reboot.
I tracked this bug to this log fragment:
Feb 24 18:04:52 ghostwheel kernel: npviewer.bin[8855]: segfault at 80000000 ip 0000000080000000 sp 00000000fffb6a5c error 14
Feb 24 18:07:28 ghostwheel kernel: hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.This started to happen after recent upgrade of ALSA and kernel. Before that FlashPlayer used to crash in FF but without messing with my sound.
EDIT:
I forgot to mention that the noise is getting worse over time. After two hours it's impossible to hear anything even after turning everything next to mute.
EDIT2:
Another update. Problem reocurred after rebooting and playing only one song in VLC. This time without any visible cause except the segfault of blueman_app:
Feb 24 19:45:59 ghostwheel kernel: blueman-applet[4377]: segfault at 7f1f7c113080 ip 00007f1f7bbe9e6f sp 00007fff389dd208 error 7 in libpython2.7.so.1.0[7f1f7bb67000+171000]But it crashed before I played the first song.
